Chemical Safety

A COSSH risk assessment must be completed prior the possession or use of any new chemical that has not been previously used. The detail in this risk assessment will depend on the hazard level of the chemical and the quantities used.

Please find more information on the hazard level of the chemical and the quantities. 

Chemical Signage

For information on hazard pictograms please refer to the HSE website


Storing Chemicals

Please refer to guidance document CHEM04 on the SEPS website.


Chemical Spills

There are a number of chemical spills kits available that can be used for chemical spills as appropriate:

  • Formaldehyde and solvent granules spill kit and chemisorb spill kit granules for acids and alkalis spills
  • In the external solvents waste store sand and granules are also available.

Chemical Accidents

  • The PI/ Line Manager and local safety co-ordinator for the building must be notified of any accident involving a chemical carcinogen or other High Hazard chemical. This will be investigated and a report sent to SEPS using the online reporting incident form.
  • If a solution is spilled on an impervious surface, wipe up the liquid carefully with paper tissues, always working from the edge inwards. Place the tissue in a yellow sack for disposal.
  • A chemical spill on a porous surface will generally necessitate destruction by incineration. Therefore always carry out operation on trays lined with paper.
  • If clothes or shoes become contaminated with a chemical they must be removed at once, and disposed of hence the reason for wearing protective clothing.
  • Skin contamination with a chemical carcinogen is serious and should never occur if appropriate protective clothing is worn. If it does occur immediately absorb as much of the contamination as possible on paper tissues, taking care not to spread further. Wash the skin with cold running water, then repeatedly with soap and water. Never use organic solvents, these spread the contamination and promote absorption. Seek medical advice and make certain the accident is reported.
